Western Renewable Resources was retained by the Fisheries Branch of the B.C. Ministry of Environment and Parks to provide an independent assessment of sportfishing opportunities and water quality with changes in regulated summer flows in the upper Nechako River and Cheslatta/Murray Lake system.
Angling and water conditions were examined at five flows in 1986 as recorded at a gauging station int he upper Nechako River: 62 m3/s (June 22-24); 115 m3/s (July 13-15); 160 (July 17-19); 189 (July 25-27); 34 (September 6-8). On average, catch rates did not change significantly between flow periods, but fishing quality and attractiveness of fishing sites declined as flows increased above 115.0 m3/s. At 160 and 189 m3/s many test fishing sites became difficult to fish and several sites could not be fished safely. Alternatively, navigation by jet-boat improved at flows above 62 m3/s.
